The difference between Python str and repr _python

Although Str (), repr () and ' operations are very similar in feature and functionality, in fact repr () and ' do the exact same thing, they return an "official" string representation of an object, which means that most of the cases can be evaluated by using the built-in function eval () To get the object back, but Str () is different. STR () is committed to generating an object's readable string representation, and its return results are generally not available for eval () evaluation, but are well suited for print statement output. Again, not all repr () returned strings can get the original object with the eval () built-in function.
That is, repr () output is friendly to Python, and str () output is friendly to the user. However, in many cases the output of these three is still exactly the same.
Everyone is interested in writing a code to compare Str,repr and "".
